One of many ex-London players at the club, Channing signed a two-year deal at Castleford following promising displays during a loan spell at the club in 2013.
The centre played four times for Cas in the spell and scored three tries, including a brace in the final day victory over Salford.
Despite missing out on the Wales squad for the 2013 Rugby League World Cup, Channing proved his worth in the Cas squad last year, even though he couldn't hold down a regular first team spot.
